Somehow, some of the people and organizations concerned with monitoring and protecting the salmon in the North Pacific region also seem to have a very good taste for online data visualization.
The original project "State of the Salmon" was noted on infosthetics a while ago, as a post from April 2007 highlighted the online application Visual MSC (with MSC short for Marine Stewardship Council Assessment).
Recently, another sophisticated and nicely designed State of the Salmon [stateofthesalmon.org] website was created, consisting of 4 different visual applications: an interactive "Hydrography" map, a dynamic network cluster view, a rich historical data view plot, and a sparkline-rich simple list view. All these graphs focus on providing more information on the loss of biodiversity of one species: the Sockeye Salmon. In recent history, the global population of sockeye consisted of 80 subpopulations. They report that a total of 17 of these are currently threatened with extinction. Data for assessement are lacking for 26 subpopulations. 5 subpopulations are already extinct.
